Definitions

  • the present invention is related to a method of manufacturing a multilayer fluorescent information carrier and more particular to the method utilizing a mixture of organic solvents for a photopolymeric composition (PPC).
  • PPC photopolymeric composition
  • optical memory media with multiple layers have been developed.
  • parasitic reflection can occur at layer boundaries. That reflection and the resulting interference impair reading.
  • Examples of such devices, utilizing the multiplayer fluorescent carrier are disclosed in U.S. Pat. No.6,039,898 and in WO 99/47327 .
  • Such carriers exhibit high recording density, contrast, and signal-to -noise ratio. It is common to use fluorescent recording materials that, when exposed to reading light at one wavelength, fluoresce at a different wavelength. The problem of parasitic reflection can be solved by filtering out reflected light at the reading wavelength. Also, since the fluorescent light is incoherent, there is no problem of interference.
  • the multilayer fluorescent information carrier comprises a photopolymerizable composition applied to a solid base having a relief pattern. A transparent film layer is applied on top of the photopolymerized composition. The three layers are spun in a centrifuge to cause a thin, even distribution of the photopolymerizable composition, which is photopolymerized. The resulting replica is separated from the relief pattern and has a fluorescent material applied thereto. Alternatively, the replica has a non-fluorescent material applied thereto, and the non-fluorescent material is made fluorescent through diffusion. Multiple information layers thus formed can be glued together to form a multilayer storage medium.
  • the principal object of the invention comprises the utilization of a mixture of at least one ketone having a boiling temperature in the range of 98-120 °C with one or more other solvents having a boiling temperature of about 80 °C or lower. This mixture is used for the photopolymeric composition (PPC) with the fluorescent dye.
  • PPC photopolymeric composition
  • a thin-layer fluorescent polymer coated with distributed fixed luminescent centers can be prepared by using photosolidified liquid polymer compositions containing luminophores.
  • a composition is spin-coated forming a thin liquid film distributed across the replica surface in conformity with the shape of its relief and consisting predominantly of photosolidified, generally by cation and/or radial mechanisms, monomers and oligomers and dopants determining spectral and luminescent, physical and mathematical, adhesive and other characteristics of the polymer coat following its solidification by UV light.
  • the liquid composition applied should possess a good spreadability on the replica surface, high adhesion, and ease of forming a liquid and solidified film uniformely spread on the surface and differentially in terms of the replica relief, which can be attained through using a specific composition as well as coating and solidification conditions.
  • Photosolidification of the composition results in a bilayer structure with a polymeric replica and thin-film fluorescent polymer coat.
  • the bilayer structure represents as a unit a single layer a fluorescent information carrier. From similarly generated single layer carriers, there can be fabricated multilayer fluorescent information carriers of various types by sealing them together.
  • a liquid composition for a thin-film polymer fluorescent information layer (IL) according to the present invention comprises:
  • the organic solvent includes a mixture of at least one ketone with another solvent.
  • Polymeric substance is prepared by mixing components consisting of Bis (3,4-epoxycyclohexylmethyl) adipate (60% wt.) and Neopentylglycoldiglycidyl ether (40% wt.).
  • the fluorescent dye (FD) Oxazine-1 is added to the PS in the amount of 0,02 mol/l.
  • the mixture of solvents consisting of 10% wt. of isobutyl-methylketone, 50% wt. of 3- methyl-2-butanone and 40% wt. of 2-propanol are prepared.
  • the PS-FD composition is dissolved in the mixture of the solvents at the temperature of 60°C degree stirred for 4 hours to obtain a homogenous 4% wt. solution.
  • the 6 pph mixed Triarylsulfonium Hexafluorophosphate salt (50% wt. solution in propylene carbonate) in ratio to the PS were applied.
  • the obtained solution is filtered and applied to the PPC-replic
  • Rhodamine-700 in amount 0.025 mol/l and 0.005 mol/l Rhodamine-800 are used as the fluorescent dye.
  • PS-FD concentration was 1.42 % wt.
  • the 4 pph mixed Triarylsulfonium Hexafluoroantimonate salt (50 % wt solution in propylene carbonate) and 6 pph mixed Triarylsulfonium Hexafluorophosphate salt (50% wt. solution in propylene carbonate) (4 % wt) are used as the photopolymerization initiator.
